His lawyer, Luca Maori, explained that he meant that he, too, is a victim of a judicial injustice, "but certainly not in the same way as them," said Maori.
Maori also said that defense lawyers did not question the Kerchers out of respect for them.
The trial was adjourned until next Friday, June 12, when Amanda Knox will take the stand to be questioned.
According to Ghirga, she plans to answer all questions put to her by her lawyers and by the prosecution. She can refuse to answer, but Ghirga said she will not.
"She really wants to tell her point of view," he said, "and if the interrogation takes place with all the guarantees, as we believe it will, it will be complete."
He added, "Amanda is innocent, because on that evening she was not on the scene of the crime."
